This paper describes an approach to footwear insole design using two techniques: a Finite Element Analysis and an experiment. The study was divided in three stages: Image Analysis from data acquired from CT scan, Finite Element Analysis and Plantar Pressure Measurements. Image Analysis stage included computer tomography of an adult male, volume segmentation of the lower leg, and mesh generation. Among the universe of insole design variables two were selected: insole profile, and material. Numerical simulations aimed at emulating shod balanced standing position, while experiment was performed under identical conditions. Numerical approach was a static analysis considering large deformation and contact. The output variable was peak plantar pressure (PPP). Experimental and simulation results point out that all two variables have influence on PPP, where custom made insoles made of soft material showed the highest amount of decrease when compared to barefoot condition.
